Auras

Auras are the remnants of lost Orokin technology. They are highly sought after by all three factions for their impressive potential to turn the tide of battle. They grant passive benefits to all team members such as health regeneration or extra ammo.

The benefits of Auras are not limited to playing only as Tenno; if a player has an Aura equipped in the active loadout of the Warframe they were using when they entered an Archwing game, the Aura will provide the same benefit in Archwing games as it does in 'normal' games – provided the benefit is applicable in Archwing games, that is. Auras such as Physique, Energy Siphon, and Rejuvenation work perfectly in Archwing games.

However, given that you do not have a secondary weapon when playing as an Archwing, the Pistol Scavenger mod, for example, is utterly useless. It will not affect you negatively, but you would be much better off putting a different Aura in that loadout slot when you want to play Archwing games.
